PATENTEU JUN] 51971 3584' 675 sum 1 BF 2 PATENTEU JUN] 5 I971 SHEET 2 BF2 MULTICOLORED FRAME FOR FOLDING FURNITURE This invention relates to aframe for folding furniture. More particularly, this invention relatesto a decorative frame for use as a back rest or seat for a foldablechair or chaise.

I-Ieretofore various folding furniture constructions have been knownwherein tubing material has been utilized for supporting an occupant. Inmany cases, in order to impart a decorative appearance to these frames,the tubing material has been made of different colors. For example, insome instances, the tubular frames have been constructed with tubes ofdifferent colors which are wound in alternation with each other so as topresent a varied pattern of colors.

However, in order to construct the heretofore used frames, such hasrequired many steps in order to position the various colored tubes ontothe frame. In addition, such has required a relatively great period oftime in order to properly place the tubing materials in their respectivepositions in order to effect the pattern of color desired.

Accordingly, it is an object of the invention to provide a frame havinga multicolor pattern thereon which is constructed in a simple manner.

It is another object of the invention to provide a frame for a foldableframe which has an attractive appearance.

It is another object of the invention to provide a multicolor frame fora foldable chair which 'iseasy to manufacture within a relatively shorttime.

Briefly, the invention provides a frame for foldable furniture such aschairs and chaises for outdoor use which has a multicolored appearance.The frame is constructed with a rigid frame, for example, of tubularU-shaped construction, and a tubing which is wound about the frame in aseries of windings to form a surface for supporting an occupant. Thetubing is constructed as a single integral piece as an extrusion havinga tube section and a cord section integrally formed together. Inaddition, the tube section is formed of a larger cross section than thecord section and is also formed with a surface of a different color fromthe surface of the cord section.

In order to assemble the frame, the tubing of the multisection issecured at one end to the rigid U-shapcd frame and wound around theframe in a series of windings. Thereafter, the remaining end of thetubing is also secured to the frame.

These and other objects and advantages of the invention will become moreapparent from the following detailed description and appended claimstaken in conjunction with the accompanying drawings in which:

FIG. I illustrates a perspective front view of a foldable chairincorporating frame of the invention therein as a seat and a back rest;

FIG. 2 illustrates a rear perspective vie of the chair of FIG. 1;

FIG. 3 illustrates a view taken on line 3-3 of FIG. 1;

FIG. 4 illustrates a view taken on line 4-4 of FIG. 1;

FIG. 5 illustrates a view of a frame of the invention during assembly;

FIG. 6 illustrates a schematic view of the manner of making an extrudedtube for the frame of the invention; and

FIG. 7 illustrates a view taken on line 7-7 of FIG. 6 illustrating across-sectional view of the extrusion.

Referring to FIGS. 1 and 2, the chair I0 is constructed with a legsupport assembly II of conventional structure as well as an arm assembly12, likewise of conventional structure. In addition, the chair It) has aseat 13 and a backrest 14, each of which is secured to the leg supportassembly I1 and arm assembly 12 for folding therewith between acollapsed and an open position. Each of the seat 13 and back rest 14 areconstructed in identical fashion and therefore only the back rest willbe further described hereinafter.

Referring to FIGS. 1, 3 and 4, the back rest I4 is constructed of aframe which includes a U-shaped frame 15, for example, of tubularaluminum construction, and an extrusion 16 which is wound about theU-shpaed frame in a series of windings I7. The extrusion I6 is formedwith a hollow tube section I8 and a hollow cord section 19. The tubesection 18 and cord section 19 are disposed along side each other inintegral relationship. In addition, the cord section 19 is formed withsmaller cross-sectional dimensions than the tube section 18, that is,for example, the cord section is of smaller diameter than the tubesection 18.

The extrusion I6 is secured to the U-shaped tubular frame 15 by suitablesecuring means 20, for example, a series of threaded screws. Thesethreaded screws 20 pass through the ends of the extrusion 16 as well asthrough intermediate sections of the extrusion 16 into threadedengagement with the U-shaped frame 15. These threaded screws 20 canfurther be provided with suitable washers or heads 21 so as to providean increased area of contact with the material of the extrusion 16 inorder to prevent a tearing away of the extrusion material from thethreaded screws 20. As shown, the ends of the extrusion 16 are securedto the inside of the U-shaped frame 15 whereas the intermediate sectionsof the tubing are secured to the rear of the U-shaped frame I5.

Referring to FIGS. 1 and 7, the extrusion 16 is formed of a plasticmaterial, such as vinyl, which has a uniform color. In addition, thecord section 19 is provided with a coating 22 of a second color which isdistinct from the color of the extrusion 16. This coating 22 is appliedto the entire exposed surface of the cord section 19 so that theextrusion is provided with a two-tone color effect.

Referring to FIGS. 6 and 7, in order to form the extrusion 16 with thecoating 22 on the cord section 19, a mass of the plastic material of theextrusion is fed through a suitable extrusion die 23 (FIG. 6) whichforms the extrudable material into the shape desired. For example, theextrusion 16 is formed into a tube section 18 of circular cross sectionand a cord section 19 also of circular cross section with both sections18, 19 integrally attached along a longitudinal surface. At this point,the extrusion would be of a uniform color throughout. Thereafter, theextrusion 16 passes through a coating assembly 24 of conventionalstructure within the extrusion machine (not shown) and the coating 22 ofcolor is coated about the cord section 19.

Referring to FIG. 5, in order to assembly the backrest frame, theextrusion 16 is secured at one end by a threaded screw 2%) to the topportion of the U-shaped frame 15 and thereafter is wound about theU-shaped frame I5 until reaching the bottom portion thereof. At thispoint, the extrusion 16 is severed and secured at the severed end as byanother screw to the U-shaped frame 15. Alternatively, the extrusion canbe initially sized to the correct length before winding onto theU-shaped frame 15. Further, as another alternative, the extrusion 16 canbe wound for a partial length along the U-shaped frame with a secondlength of extrusion 16 being wound about the remainder of the U-shapedframe. Depending upon the overall length of the extrusion 16, one ormore threaded screws 20 can be secured along intermediate sections ofthe extrusion to further maintain the windings of the extrusion inproper position on the U-shaped frame 15.

The invention thus provides a frame for foldable furniture with asupport surface which has a two-tone effect and which is constructed ina relatively simple manner. The support surface of the frame is formedof an extrusion of multisectional construction wherein one section isformed of one color and a second section is coated with a second color.For example, the larger section can be made of a turquoise color whilethe smaller cord section is coated with a dark blue color. Further,while the respective sections of the extrusion can be provided withdifferent colors, the sections can also be provided with differentshades or tones of the same color such as light olive section and a darkolive section.

The invention further provides a frame which can be easily assembledwith a two-tone appearance. That is, since the extrusion is integrallyformed with a tube section and a cord section of different colors, it isonly necessary to wind the extrusion about the tubular U-shaped frame ina single step operation. Furthermore. because of this single stepoperation, the

relative position of the tube section to the cord section remains fixedat all times so that no separation between the various sections occurswhich would otherwise disrupt the aesthetic appearance of the chair inwhich the frame is incorporated. Further, by forming the extrusion oftwo sections of 5 a rigid frame, and

a plastic tubing extrusion secured to and wound around'said frame toform a support surface, said extrusion having a hollow tube section anda hollow cord section integrally formed together, said tube sectionhavinga surface of a different color from the surface of said cordsection and being of larger cross section than said cord section, and

said cord section has a coating thereon of a different color from thecolor of said tube section.
